GPS Or GPS APP on smartphone

And put boundaries in before going out :-

tenement;

with blocks;

zooming in always there - accurate to v close;

and if your not watching you could walk over your boundaries;

Done with dedicated gps. Can same be done with phone gpss? (their available software seems to be offering more and more)

Not sure Jon, but here's my take on the tech I have.

eTrex20 - used to waypoint the car and if I lose direction back to it I have the GPS. Also I note sun position, time etc.

I navigate Vic tracks using an Android 7" dash tablet with dedicated GPS antenna, Oziexplorer and Vicmap. It plots the track I take. The software is also available on laptop where tracks can be created and downloaded to the tablet. Logs on tablet can also be uploaded to the laptop.

As I have an Android Samsung Galaxy phone also with a dedicated GPS antenna Ozi is on it as well and tracks and waypoints are seamlessly transferred on all 3 either way.

Ozi 3D, with height data will also generate 3D bitmaps of any area as a snapshot of hills, creeks re-entrants etc.

I have also scanned, calibrated and converted all of the Doug stone maps to run in Ozi as well.

With that data at my finger tips, getting lost is the least of my worries.

As an aside a good compass, don't go flat, don't need a signal and don't cost much.

That's an interesting one condor22 - I have a Galaxy as well, but never tried the mapping/GPS on it as only bought it for phone calls, take a few pics etc and could never trust any data charges that could deplete the account - was always a worry in the bush when seemingly for no reason it'd be trying to go on the net and do something. Even found half way through our trip that somehow the pixel resolution set itself from max to min. Didn't know until I got back grrr.

What is a dedicated GPS antenna? If a little ~$100 add on, couldn't you have used your eTrx20 instead?

You mentioned

The software is also available on laptop where tracks can be created and downloaded to the tablet.

So, am guessing but this suggests you should be able to create boundaries/tenements etc, at least as tracks/routes, and then download to your tablet.

To help when files are wrong format / datum etc have used open source Qgis. Brilliant for editing .kml .shp etc Maybe you have a similar method from having calibrated (georeferenced) your maps?

I use a handheld garmin etrex30 There have a lot more options than phone. I sometimes use google earth to mark points and parts of tracks and send data to gps so I can locate where Ineed to go.

sample data I get when return what can be seen, A paddle around the lake I did.

When I refer to a dedicated GPS antenna, the Samsung Galaxy S3 I have has an inbuilt antenna separate to the phone signal, in other words it does not use the provider network. Oziexplorer for Android is an App I installed on the phone, the map files are on a data card in the phone. Therefore I can use it as a GPS without a phone signal and without Data charges.

Re Boundaries in short, create on laptop and download to tab or Samsung phone.

Doug Stones maps are reasonably accurate and are marked with Grid coordinates. I can take a .jpg picture of a map and there is a calibration utility within the PC version of Ozi.

Thanks condor22. Always another trick or 2 to learn.

To give the link to GPS

We have a couple of Garmin Rino 650's, which allow us not only the usual features of a GPS, but also talk via UHF [40 channel] or send texts [via satellite - no sim.

BUT

to answer the question within the OP.

prior to the Rino's we had a free app called Park my Car , which was obviously made for shopping centre car parks, but worked very well on the galaxy
right throughout the triangle.
